Fig. 1 is a kind of Data Radio Bearer (Data Radio Bearer, DRB) mapping side provided in an embodiment of the present invention Method schematic flow sheet, the flow show the handling process of network side, comprises the following steps 101 to step 102:

Step 101, the network equipment determines DRB mapping mode;The mapping mode of the DRB refers to whether DRB allows to reflect It is mapped on licensed band carrier wave and/or whether allows to be mapped on unlicensed frequency range carrier wave.

Wherein, the mapping mode of DRB described in the embodiment of the present invention is including but not limited to following two:First mapping mode With the second mapping mode.First mapping mode refers to that DRB only allows to be mapped on licensed band carrier wave;Second mapping mode refers to DRB both allows to be mapped on licensed band carrier wave or allows to be mapped on unlicensed frequency range carrier wave.

Step 102, the network equipment is according to the DRB determined mapping mode, sent on specified carrier wave described in DRB business datum.

In a step 101, the network equipment can be according to DRB service quality (Quality of Service, QoS) spy Point and/or wireless spread-spectrum technology (Radio Link Control, RLC) transmission mode, determine DRB mapping mode, the net Network equipment can also follow the DRB to make an appointment mapping mode, the business so that those have certain requirements to quality of service Data (such as Online Video, game) are not sent on unlicensed frequency range carrier wave, avoid unlicensed frequency range carrier wave noncontinuity Quality of service caused by traffic delay increase caused by work and delay variation reduces, and can be effectively improved the business body of user Test.

Preferably, the network equipment, can be according to set in advance when determining DRB mapping mode according to QoS features QCI (QoS Class Identifier, QoS grade) and DRB mapping modes mapping table.In standard agreement, definition Two types business:Ensure bit rate (Guaranteed Bit Rate, GBR) and non-guarantee bit rate (Non Guaranteed Bit Rate, GBR), and 9 kinds of QoS grades, as shown in table 1.The DRB for each transmission services that terminal is established All correspond to a QoS grade.In the embodiment of the present invention, DRB mapping modes corresponding to this 9 kinds of QoS grades settings can be directed in advance, Such as the QoS grades less than or equal to 5, DRB mapping modes corresponding to setting are only to allow to be mapped to authorization frequency range On carrier wave, so, when the network equipment carries out DRB mappings, it can be obtained according to the DRB QoS ranked queries mapping table To corresponding DRB mapping modes.

Further, in the embodiment of the present invention, the network equipment can determine DRB mapping side on a variety of different opportunitys Formula, for example DRB mapping mode can be determined on following one or more opportunitys:

When DRB is established, according to DRB QoS features and/or RLC transmission pattern, it is determined that the DRB established mapping side Formula;

After DRB foundation, according to signal interference situation and/or the quality of reception of transmission services, redefine and configure institute The DRB of foundation mapping mode;

The network equipment receives the DRB mappings for the switching terminal that source network device is sent as switching destination network device After mode information, redefine and configure the DRB of switching terminal mapping mode.

In the above embodiment of the present invention, DRB mapping mode is determined by the network equipment, and mapping mode is indicated to Terminal, according to the DRB determined mapping mode, the network equipment and terminal send DRB business datum on specified carrier wave, It is achieved thereby that in licensed band resource and/or unlicensed resource of frequency range transmitting data.

Fig. 2 is another DRB mapping methods schematic flow sheet provided in an embodiment of the present invention, and the flow show end side Handling process, comprise the following steps 201 to step 202:

Step 201, terminal determines DRB mapping mode;The mapping mode of the DRB refers to whether DRB allows to be mapped to On licensed band carrier wave and/or whether allow to be mapped on unlicensed frequency range carrier wave.

Wherein, the mapping mode of DRB described in the embodiment of the present invention is including but not limited to following two:First mapping mode With the second mapping mode.First mapping mode refers to that DRB only allows to be mapped on licensed band carrier wave;Second mapping mode refers to DRB both allows to be mapped on licensed band carrier wave or allows to be mapped on unlicensed frequency range carrier wave.

Step 202, the terminal sends the business number of the DRB according to the DRB mapping modes on specified carrier wave According to.

In step 201, terminal can determine DRB mapping mode by following two modes.

Mode one:The configured information that terminal is sent according to the network equipment, DRB mapping mode is determined, in the configured information Indicate the DRB of terminal mapping mode;Terminal receives the configured information by radio resource control RRC signaling:In RRC signaling Comprising the first DRB lists and the 2nd DRB lists, the DRB in the first DRB lists both allows to be mapped on licensed band carrier wave Also allow to be mapped on unlicensed frequency range carrier wave, the DRB in the 2nd DRB lists does not allow to be mapped to unlicensed frequency range carrier wave On.

Mode two:Terminal follows the DRB to make an appointment mapping mode, for example, RLC patterns of having made an appointment are UM's DRB is only capable of being mapped on licensed band carrier wave, and RLC patterns can be mapped to licensed band carrier wave for AM DRB and can also be mapped to On unlicensed frequency range carrier wave, then terminal follows this agreement to determine DRB mapping mode.

In the embodiment of the present invention, the terminal can determine DRB mapping mode on a variety of different opportunitys, for example, can with Under one or more opportunitys determine DRB mapping mode:

When DRB is established, terminal receives the first configured information that the network equipment is sent, and is determined according to the first configured information DRB mapping mode, the DRB of terminal mapping mode is indicated in first configured information.

After DRB foundation, terminal receives the second configured information that the network equipment is sent, and is determined according to the second configured information DRB mapping mode, the mapping mode for the DRB that the network equipment reconfigures for terminal is indicated in second configured information.

After terminal is switched to destination network device, receives the 3rd configured information that destination network device is sent and determine DRB's Mapping mode, the mapping mode for the DRB that destination network device reconfigures for terminal is indicated in the 3rd configured information.

In the above embodiment of the present invention, DRB mapping mode is determined by terminal, and according to the DRB mapping modes, The business datum of the DRB is sent on specified carrier wave, it is achieved thereby that in licensed band resource and/or unlicensed frequency range Transmitted over resources data.

Further, after terminal determines DRB mapping mode, the data to be transmitted for carrying DRB is sent to the network equipment The BSR of amount, specifically BSR can be reported using following three kinds of modes.

Mode one:Mapping logical channels corresponding to the up DRB that terminal will be transmitted on different classes of carrier wave are to different Logic channel group.

For example, logic channel 0~3 can only transmit on licensed band carrier wave;Logic channel 4~9 may map to license Transmitted on frequency range carrier wave or unlicensed frequency range carrier wave;So, can be by two logic of class when DRB is mapped into logic channel group Channel is mapped to different logical groups, such as:Logic channel 0 and 1 is mapped to logic channel group 0;Logic channel 2 and 3 is mapped to Logic channel group 1;Logic channel 4,6,7,8,9 is mapped to logic channel group 2;Logic channel 5 is mapped to logic channel group 3.

When the BSR that the network equipment is received for logic channel group 0 and 1 is reported, it is known that these data volumes can only permitted It can be transmitted on frequency range carrier wave;The BSR received for logic channel group 2 and 3 is reported, and is known that these data volumes can carry in two classes Transmitted on ripple.

Mode two:Terminal reports two class BSR, a kind of only to be only capable of transmitting on licensed band carrier wave comprising each logic channel group Data volume;The another kind of data that can be transmitted comprising each logic channel group on unlicensed frequency range carrier wave or licensed band carrier wave Amount.
